Herein, a new series of conjugated polyacetylenes having conjugately linked fullerene and porphyrin groups as pendant units were prepared by copolymerization catalyzed by [Rh(nbd)Cl]2-NEt3. The thin films of copolymers produced a steady and prompt photocurrent at irradiation of 20.0 mWcm-2 white light. The SEM image indicated uniform nanorods morphology of the copolymer was formed with a diameter of about 100 nm and a length of about 300 nm. Attaching porphyrin and fullerene units to polyacetylene backbone in g-conjugated way greatly improved the redox properties and enhanced the photocurrent response.
